Description

Technical Field

[0001] The utility model relates to the technical field of printed circuit board processing, in particular to a PCB board splitting device. Background Art

[0002] In the field of electronic manufacturing, a printed circuit board (PCB) is a core component of electronic products. The precision and efficiency of its processing procedures directly affect the performance and production cost of electronic products. As a key link in the PCB production process, the significance of the PCB splitting process is to divide a large PCB panel into individual small boards for subsequent assembly and application.

[0003] With the development of intelligent technology, the traditional manual sorting method has gradually been replaced by automated equipment. In modern PCB sorting processes, manipulators are often used to control suction cups for sorting. However, during the milling cutter cutting process, PCB board debris is easily generated, which affects the suction efficiency of the manipulator suction cups, resulting in problems such as inability to suck and dropping during the sorting process. Content of the Utility Model

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is to propose a PCB board splitting device, adopting the following technical solutions:

[0005] A PCB board splitting device includes a frame, on which a cutting station, a dust suction station and a material receiving station are arranged; a cutting assembly is arranged at the cutting station for splitting the PCB board; a suction nozzle assembly is arranged at the material receiving station for sucking and transporting the split PCB board; the dust suction station is arranged between the cutting station and the material receiving station, and is provided with a dust suction assembly, which is equipped with a lifting mechanism for controlling the up and down movement of the air nozzle, and the air nozzle is equipped with an upper cover plate, and the upper cover plate is provided with a number of partition bars;

[0006] It further includes a transportation mechanism, which includes a first slide rail and a first movable table, and the first movable table reciprocates between the cutting station and the material receiving station through the first slide rail; the upper end surface of the first movable table is used for placing the PCB board.

[0007] For further improvement, support columns are arranged on both sides of the frame. A first guide frame and a second guide frame are respectively erected between the two support columns perpendicular to the direction of the first slide rail. The cutting assembly is slidably arranged on the first guide frame, the suction nozzle assembly is slidably arranged on the second guide frame, and the dust suction assembly is fixedly arranged between the first guide frame and the second guide frame.

[0008] For further improvement, the above-mentioned dust suction assembly includes a housing, in which an air pump and a hydraulic rod are arranged. The push rod of the hydraulic rod extends downward to the outside of the housing to form the above-mentioned lifting mechanism. The lower end of the push rod is connected to the nozzle, and the nozzle is connected to the air pump through a dust suction pipe.

[0009] For further improvement, the above-mentioned housing is provided with a plurality of connecting pieces for connecting the first guide frame and the second guide frame.

[0010] For further improvement, a circular flange is provided at the lower end of the nozzle, and an elastic clamping member for clamping the circular flange is provided on the upper cover plate.

[0011] For further improvement, the spacing distance between several of the above-mentioned partition bars is smaller than the width of the split PCB board.

[0012] For further improvement, the distance between the nozzle and the PCB board is 2 cm to 5 cm.

[0013] For further improvement, the above-mentioned conveying mechanism further includes a second slide rail, and a second movable table is arranged on the second slide rail; it also includes a groove, the first slide rail and the second slide rail are arranged on the inner side wall of the groove, and the second slide rail is arranged at the lower end of the first slide rail.

[0014] For further improvement, the above-mentioned cutting assembly is a milling machine and its supporting components.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] First, the present utility model integrates the cutting station, the dust suction station and the material receiving station, realizing the full-process operation from cutting, dust suction to material receiving, and improving the production efficiency. Among them, the dust suction station is to solve the problem that the residual debris on the board after cutting the PCB board affects the material receiving process. When there is debris on the PCB board, if the suction nozzle assembly at the material receiving station is contaminated with debris, it is easy to cause the suction cup to fail to achieve a sealing effect, resulting in inability to suck or drop during transfer. Adding a dust suction process between the cutting station and the material receiving station can reduce the occurrence of the above situations and improve the production efficiency.

[0017] Second, the dust suction assembly of the present utility model is provided with a hydraulic rod. When dusting the cut PCB board, the nozzle can be lowered close to improve the dusting efficiency. At the same time, an upper cover plate is installed at the nozzle, and the upper cover plate is provided with a plurality of partition bars, which can prevent the PCB board from being accidentally sucked in when processing thin PCB boards.

[0018] Thirdly, the utility model is provided with a first movable table and a second movable table. When the PCB board carried by the first movable table is cut and transferred to the material receiving station for material receiving, the second movable table can carry another group of PCB boards for cutting. By opening a groove on the frame, the second movable table exchanges positions with the first bearing table from the groove to realize the simultaneous operation of the two groups of operations, improving the working efficiency of the overall equipment.

[0033] This application provides a PCB board splitting device, as Figure 1 and Figure 2 shown, which includes a frame 100. A cutting station 10, a dust suction station 20, and a material receiving station 30 are provided on the frame 100; a cutting assembly 11 is provided on the cutting station 10 for splitting the PCB board; a suction nozzle assembly 31 is provided on the material receiving station 30 for sucking and transporting the split PCB board; the dust suction station 20 is arranged between the cutting station 10 and the material receiving station 30, and a dust suction assembly 21 is provided for sucking the residual debris on the PCB board after cutting.

[0034] Figure 1 What is shown is the material receiving station 30 of this device. The suction nozzle assembly 31 is arranged directly above the station. The motor is controlled by the control system. The motor drives the transmission system to transmit the suction nozzle to the required position. The transmission system can be components such as a gear set, a transmission belt, a lead screw, or a combination thereof. The suction nozzle is lowered to a suitable height. The suction nozzle is connected to a vacuum pump through a vacuum pipeline, and the PCB board is sucked by using the method of pumping vacuum. Then, the suction nozzle is driven to move upward by the control system and transferred to the material receiving tray on the right to achieve material receiving. The application of mechanisms such as the motor, the transmission system, and the vacuum pumping assembly in this field all belong to the prior art, so they are not shown in the figure and will not be elaborated here.

[0035] Figure 2 What is shown is the cutting station 10 of this device. The cutting assembly 11 is arranged directly above the station. Specifically, the cutting assembly 11 in this embodiment is a milling machine and its transmission system. Before cutting, the cutting path is preset according to the PCB board to be processed. The control system sends an instruction to the motor to drive the milling cutter to the indicated position, and then drives the milling cutter to descend for cutting. After cutting, the milling cutter is moved upward again to transfer the PCB board to the next process. The application of mechanisms such as the motor and the control system in this field also belongs to the prior art, so they are not shown in the figure and will not be elaborated here.

[0036] As Figure 3As can be seen from the structural schematic diagram of the dust suction assembly 21 shown, the dust suction assembly 21 is equipped with a lifting mechanism 22 for controlling the up and down movement of the nozzle 23. A top cover plate 24 is provided at the lower end of the nozzle 23, and a number of partition bars 241 are arranged on the top cover plate 24.

[0037] Specifically, the dust suction assembly 21 includes a housing 25. An air pump and a hydraulic rod are arranged inside the housing 25. The push rod of the hydraulic rod extends downward to the outside of the housing 25 to form the above-mentioned lifting mechanism 22. The lower end of the push rod is connected to the nozzle 23, and the nozzle 23 is connected to the air pump through a suction pipe 26. The internal structures of the air pump and the hydraulic rod are not shown in the figure, and those skilled in the art should be able to understand and apply the implementation.

[0038] As Figure 3 shown, a circular flange 231 is provided at the lower end of the nozzle 23, and an elastic clamping member 242 that is clamped to the circular flange 231 is provided on the top cover plate 24. Through the quick-release structure of the elastic clamping member 242 and the circular flange 231, it is convenient to replace the top cover plate 24 with different shapes when processing different types of PCB boards. The replaced top cover plate 24 needs to meet the requirement that the spacing distance of the partition bars 241 is less than the width of the split PCB board to avoid accidentally sucking the PCB board when the suction force is set unreasonably. In addition to adjusting the appropriate suction force, the distance between the nozzle 23 and the PCB board should also be controlled. In a specific embodiment, this distance is controlled between 2 cm and 5 cm, and those skilled in the art should be able to understand and appropriately adjust the distance between the nozzle 23 and the PCB board.

[0039] As Figure 1 and Figure 2 shown, support columns 200 are provided on both sides of the frame 100. A first guide frame 210 and a second guide frame 220 are respectively erected between the two support columns 200 perpendicular to the direction of the first slide rail 110. The above-mentioned cutting assembly 11 is slidably arranged on the first guide frame 210, the above-mentioned suction nozzle assembly 31 is slidably arranged on the second guide frame 220, and a dust suction assembly 21 is fixedly arranged between the first guide frame 210 and the second guide frame 220.

[0040] Combined with Figure 3 , four connecting members 27 for connecting the first guide frame 210 and the second guide frame 220 are provided on the housing 25 of the dust suction assembly 21. Preferably, the connecting member 27 is fixedly arranged on the first guide frame 210 and the second guide frame 220 through bolts, which makes the overall structure compact. The dust suction assembly 21 does not occupy extra space, and when the PCB board is transferred to the material receiving station 30 after cutting, it must pass through the dust suction assembly 21, and the path planning is reasonable, improving the work efficiency.

[0041] As Figure 1 and Figure 2As shown in the figure, the device further includes a transportation mechanism, which includes a first slide rail 110 and a first movable table 111. The first movable table 111 reciprocates between the cutting station 10 and the material receiving station 30 through the first slide rail 110. The upper end surface of the first movable table 111 is used for placing PCB boards.

[0042] As Figure 1 and Figure 2 shown in the figure, a groove 101 is further formed on the frame 100. The above-mentioned first slide rail 110 is arranged at a position close to the upper inner side wall of the groove 101, and the first slide rail 110 straddles the cutting station 10 and the material receiving station 30. In addition, a second slide rail 120 is further included, and a second movable table 121 is arranged on the second slide rail 120. Similar to the first slide rail 110, the difference is that the second slide rail 120 is arranged at a position close to the lower inner side wall of the groove 101, below the first slide rail 110. Correspondingly, a lifting table 122 is arranged on the second movable table 121 in a liftable manner, and the upper end surface of the lifting table 122 is used for placing another group of PCB boards.

[0043] In a specific embodiment, a group of PCB boards are carried on the first movable table 111 for cutting. When this group of PCB boards are cut, after being sucked by the dust suction station 20 and moved to the material receiving station 30, after the second movable table 121 places another group of PCB boards on the lifting table 122, the lifting table 122 is raised below the cutting station 10. After cutting is completed, it remains in the raised state and moves to the dust suction station 20 for dust suction. After dust suction is completed, the lifting table 122 descends. At this time, if the previous group of PCB boards are collected, the first movable table 111 is moved back below the cutting station 10 to perform the next cycle of operation, while the second movable table 121 moves to the material receiving station 30 to perform the material receiving process. Through the above structure, the second movable table 121 exchanges positions with the first carrier table from within the groove 101 to enable two groups of operations to be carried out simultaneously, improving the working efficiency of the overall equipment.

[0044] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
